`IMPROVEMENT IN `APPARATUS FOR STRIPPING T HE TOP-FLATS OF CARDlNG-MACHINES.

Specicatiou forming part of Letters Patent No.` 113,339,` dated April 4, 1871.

To all whom it may concern Beit known that I, EENEsT GoNs'rANTIN PFAFF, of Chemnitz, in Saxony, have invented certain new and` useful Improvements in Cardin g-Engines and I' do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specitcation.`

This invention relates to those cardingengines for which Letters Patent were granted in England to George Wellman' on the 11th of September, 1860, numbered 2,190, and known as VVellmans Patent Carding-Engines.7 In those carding-engines the flats are stripped by seltacting apparatus; and this invention consists in certain improved combinations of machinery for stripping the iiats near the licker-in oftener than those near the doffer, and in being able to vary the order of succession in which they are stripped.

In performing this invention the radial arm s and cani-wheels are made as usual, and disks with projections and recesses on their circumferences are employed to govern the order of succession in which the top-flats are lifted.

The lifting-slides are made in two parts, and to the upper part of one of each of them is jointed a weighted elbow-lever, the lower end of which forms a catch.

Figure l is a side view and partial vertical section, and Fig. 2 an end view, of the principal parts of a Wellman carding-engine, to which my improvements are applied.

co is part of the main cylinder. b b are the radial arms, one being mounted at each end of the axle of the main cylinder. c is one of the top-flats d, the:stripper, and c the cam-wheels,

4 mounted on the studs f, fixed in the radial arms b.

The parts above enumerated, and the mechanism consisting of the segmental rack z z, and other parts sho-wn in Figs. l, 2, and 6, for moving the radial arms, are made, as in Wellmans carding-engine, of the usual construc= tion.

0n the outer ends of the studs j' are mounted the disks or division-plates g, the circumferences of which are made with projections and recessed, as shown best in Fig. 2.

To the back of thedisks f are castor fixedv into the pinions h2, and turn the pinid'ns 71l and curved plates h1 one-fourth round, thereby7 moving the disks g the distance required for one top-ilat. While the curved plates are performing this fourth of a revolution their corners pass through openings in the lafnges e2 of the cam-wheels e, after which the curve of the plate lits on the ilange c2 to hold the division-plate g steady. i

The radial arms b are made with slots, as usual, to guide the slides by which the top-flats are lifted; but these slides are now made in two parts, as shown best in the detached views, Figs. 3, 4, and 5.

The main slide, i, moves up and down in the radial arm, and the second slide, t', fits in the slot of the radial armand on a ribbed projection on the main slide. The slide i has projections, between which the end of the top-fiat enters.

To each slide i is jointed a weighted elbowlever, j, the lower end of which forms a catch, jl, which is held under the lower end of the slide i by the weight jz. When the slides descend, the lower sides of the weightsj2 either come in contact with projections on the disks g, or they enter the recesses between the said projections. If the weights come on projections, the catches jl are moved from under the slides i', and the slides 'i then rise without lifting a top-flat. If, on the contrary, the weights jl, in descending, come into recesses in the disks g, the catches jl are not moved from under the slides i', and then all the slides, together with a top-at, are raised by the cam= wheels e, and the top-tlat is stripped by the stripper d, in the usual manner. g

The top-flats c, when down, are supported, as usual, on the ends of the setting-screws y, passing through the rims al, as shown in Fig. 11, and they are steadied by the studs a2, as usual. When the top-flats are raised they are guided by the round or other-shaped studs k,

projectin gfrom the cross-rail b', connecting the radialfarms bi*y These-studs la.are'taperJpoi-nted;1

sion indicated in the diagram, Fig. l2.- The. top-flats are numbered'consecutively froml1v to 18, the number l being near the licker-in. In the iirst traverse of the radial arms the first,

third;V fifth, ninth", eleventh', and'lifteenth'top-1V i iiats are stripped, as indicated by the crosses in the diagram; and iny the return traverse the sixteenth, twelfth', tenth, sixth, fourth, andA jand vthe radial arms oi" top-'fiat-stripplngv. ap-

second top-ilats arev stripped; and 'at the seeond and third to-and-fro vtraverses-f of theradialarins the top-Hats indicated'by'erossesare stripped. By thi-s diagram it will be seen that 'during these to-and-fro traverses of vthe radial arms the six top-flats near the licker-in are stripped three timeseach, the six top-flats near the dofl'er are each'. strippedonce, land,` thefsix intermediatev top-flats are each stripped twice", b'utby varying the number and size of th'eprojections on the division-plates g, the

order oi'succession can. be Varied: according. to the number of'topfiila-ts employed, and' the j number of tiines it'mayb'e desirable to stripv some of the top-flats oftener than the oth'ers.-

The top-flat is shown inFigs-7, 8, 9,10,I

holes containing Wood pegs. The card-sheets ,are secured to the top-,flat by nails driven in the said Wood pegs.

i The upper part of the top-flat consists of a piece oflwoodf, c2,`Y Whicl issecured' to the plate 'c1'by-Wood1-screws, as shown in Figs. 7 and 9. The ends of the top-flats consist of the plates ,03, onwhich the consecutive numbers are cast, Las shown -in Fig. 10. These plates are'sorewed ,to the plate c1, and serve as a protection to ,the ends of the vWood o2.
